WORKING BARREL.

Application filed May 18,

This invention relates to a working barrel,-

and particularly to a construction designed for a deep well pump wherelna proper packing and valve operation 1s required commensurate with thepressures present 1n the liquid to be pumped.

In the use of a working barrel carrying a standing valve at its lowerportlon, it s important to provide the traveling valve member withpacking engaging the barrel and to maintain such packing under yieldingpressure in contact with thewall thereof. This result I accomplish veryefiicientlylby the use of aaloos'ely mounted head WhlCll protects thepacking against the entrance of sand or foreign matter and is recessedto receive a pressure device and also extended upward to permit the freeflow of liquid at the discharge from the conduit communieating, with thetraveling valve. This up- .ward extension of the-head involves areduction in the diameter of its wall so as to form a space whichcooperating with the discharge of liquid prevents the settling orcollection of sand in the intermediate space.

which would eventually result in its working into contact with thepacking surface.

Further, in the use of both the traveling and standing valves in theworking barrel of a pump it is necessary to provide means to assure aproper guiding of the ball member of these valves so that its accuraterelation to the seat is constantly maintained and any escape of liquidabout the ball when 85 seated is prevented. These advantages are securedby my construction of the valve casing with an enclosed crown andinteriorly extended guide ribs disposed to be engaged by the ball of thevalve to insure its accurate 4 seating and its free movement when liftedfrom said seat. -It is alsofound desirable to provide the valve casingwith coupling connections at its opposite ends and the series ofintermediate radial ribs with flat guiding faces to engage the ball andwith a chamber at the upper end of such ribs formed with a transversestop bar to limit the upward travel of the ball.

The invention has for an object to provide a novel and improvedconstruction in which the working barrel is provided with a travel ingvalve havin an upwardly extending delivery conduit t erefrom with apacking in terposed between the barrel and conduit, and

barrel, such head being provided with a re-,

cess to receive a compression spring disposed beneath the delivery ofthe conduit and with a reduced wall extending upward above said deliveryto create a proper current of liquid which will wash clear any sedimentor abrasive matter which might settle into the ect the packing recessand eventually a member.

A further object of the invention is to provide a novel construction ofvalve casing adapted for use for either the traveling or standingvalve'and provided at its Opposite ends with coupling connections, suchcasing being formed with a series of radial ribs having contact facesextending upward from the valve seat and a stop bar extendedtransversely above said, faces within an enlarged portion of the casing.

Other objects and advantages of the invention will be hereinafter setforth and the novel. features thereof defined by the 'appended claims.

In the accompanying drawing:

Figure 1 is a vertical section and Figure 1 a continuation thereof;

Figure 2 is a detail section of the valve casing;

-Figure 3 is a section Figure 2; and

Figure 4 is a similar view on the line 4 4 of Figure 2. Y

Like reference numerals designate corresponding parts throughout theseveral fig- 'ures of the drawing.

The numeral 10 designates the working barrel of a pump which ma be ofany deslred constructiomor siz'e depending upon the capacity thereof forpumping pur oses. The upper end of this barrel is pIOVldB with adischarge bushing 11 having a threaded connection at 12 therewith anddischar e on the line 3 -3 of passages 13 while the central portion of te ushing forms a bearin 14 for the valve stem or rod 15 which 18connected by a coupling 16 with a sucker rod of the usual type asindicated at 17. The lower end of r t e stem 15 is threaded into aported coupling 18 the discharge openings 19 of which are at the sidesthereof. This coupling at its lower end has a threaded connection with apipe or conduit 20 extending upward from the traveling valve 21. Thisvalve is a particular construction and will be. more specificallydescribed. Surrounding the conduit 20 and enga ing the walls of thebarrel 10 a proper pac ing 22 is provided and in order to secure thenecessary contact this packing is held under compression by means of ahead 23 which is slidingly mounted at 24 upon the conduit and has asliding contact with the inner face of the barrel. This head is formedwith a downwardly tapering recess 25 adapted to receive a compressionspring 26 disposed between the base of the recess and the lower portionof the coupling 18. The walls of the head above this recess are reducedin diameter as at 27 so as to properly space them from the dischargeports of the coupling and provide an annular chamber by whichan upwardmovement of the liquid is always maintained and the collection of sandor sediment in the lower portion of the head ractically prevented. Suchresult is also acilitated by car ing u ward the reduced portion 27 ofthe ead a ove the coupling, as indicated 'at 28 where the beveled edge29 thereof merges into contact with the inner wall of the barrel. Theconduit is provided beneath the packing 22 with a seat member 30 looselymount- 7 ed thereon and one or more cupwashers 31 mounted upon theconduit and held in position thereon by the threaded connection of thetraveling valve with the lower end of the conduit. The lower end of thebarrel 10 is provided with my im roved construction of. standing valve32 w ich has con led thereto the usual packing cups 33 an in- 15 take34.

larged interiorly threaded o ning 37 which is adapted torecive theretaining member 38 which engages and supports the valve seat 39 inposition. The ange 40- of this seat is adapted to engage .the under faceof an interior flange 41 at the lower portion of the casing and'fromwhich a series of radial interiorly extending ribs "41;,extend' upwards"These ribs merge at their lower 1; ends 42 into the flange 41 and theinner or contact face 43 thereof is flattened or finished so as tosecure an accurate and smooth contact with the ball 44 of the valvemember. The upper ends of these ribs are beveled as at 45 and terminateat a chamber 46 which permits free egress of the liquid about the ballwhen in raised position and contacting with the transverse bar 47 formedin this chamber 46 so that a free flow of liquid is obtained at alltimes. 76

The valve casing with. its guide ribs is adapted to be formed as acasting and these ribs are initially molded with an apex as indicated bydotted lines at 48 in Figure 4. This apex is subsequently removed bygrind- 8O ing or other methods so as to form the final curved. face 43for guiding contact with the ball of the valve. To facilitate thismolding one of the faces 49 of the ribs may be inclined and the oppositeface 50 formed straight.

In the method of producing these castings they may be formed from steelin which event it is: desirable to subject them to a picklin operationin order to remove core to sand be ore the machining of the ribs and toreduce thetool expense in the production of the completed casing.

The standin valve, as before stated, is substantially t e same inconstruction as 05 the traveling valve, differing only therefrom in theprovision of a reduced extericrly threaded coupling 51 at its upperportion.

It will be understood that this construction of valve is adapted for useas either a traveling or standing valve and also for other purposeswherein a crowned valve of this character is found desirable. 'The 0eration of the invention will'be apparent mm the foregoing descriptionfrom 1 5 which it will be seen that the head member being tensioned isalways in proper contactwith the packing and protects the same againstthe entrance 'of sand while the upward extension of this head provides aseat 1 0 for the tensioning spring and a wall extending parallel to thedischarge from the traveling valve so "as to create a proper flow atthls point which will prevent the collection of sediment. 'The travelingand standin valve members also cooperate in a pump 0 this characterdesigned for deep well work by insuring a proper seating of the ballmember to prevent leakage of liquid and loss of lifting capacity in themovement of 1 the parts in one direction and to provide a free movementof these valve members in an op osite direction of travel. The inventiont erefore presents a simple, eflicient and economically manufacturedconstruction of 3; working barrel designed to secure the'most eflicientresults.

" 'While the specific construction of the sev-' cral parts has beenshown and described, the invention is not confined thereto as 7 outeparting from the-spirit of the invention as defined by the followingclaims.
